[Ffmpeg-devel] Bug? Subtitles not detected in vob

[Wolfram Gloger]

Hi,

I can't fully, at this point.  Needs more investigation.

This one fixes the issue at hand.  I would also argue it to be
correct, since "av_estimate_timings" isn't called
"av_estimate_timings_at_start_of_stream"?

Obviously av_estimate_timings is at some stage called _within_ the
stream and not at the start of the stream (this needs to be looked at
further..).

> 2. it returns to the file position where it was before calling this func

Although this does not affect the issue at hand (just checked), I
would propose this change also because it makes av_estimate_timings
more generic (i.e. it can be called after seeking).
